BlueOptics QSFP-40G-ER4L Compatible QSFP+ Transceiver, LC Duplex, 40GBASE-ER4L, 25 km, Single-Mode Fiber

The BlueOptics QSFP-40G-ER4L is a high-performance, hot-pluggable QSFP+ transceiver designed for 40 Gigabit Ethernet applications. It is fully compatible with Synology QSFP-40G-ER4L equipment and offers reliable connectivity over single-mode fiber at distances up to 25 km. This transceiver utilizes four CWDM wavelengths (1271nm, 1291nm, 1311nm, 1331nm) and supports Digital Diagnostic Monitoring (DDM) for real-time performance tracking.

Advantages

Cost-effective alternative to OEM transceivers without compromising quality or performance. Supports 40GBASE-ER4L standard, ensuring seamless integration into existing networks. Low power consumption (<3.5W) and wide operating temperature range (0°C to 70°C) make it suitable for demanding environments.
